Hello everyone,(adsbygoogle = window.adsbygoogle || []).push({});

Suppose a situation where you have a broad plane-parallele beem of electrons wich is perpendiculary incident upon a thin foil wich scatters the e- for an angle X. I did calculus and the ratio of flux density below the foil respect with the foil remove is 1.06. But, What are the ratio of the number of e- per cm2 passing through a plane just behind (and parallel to) the foil to what with the foil removed? I thing the ratio must be 1.06, also.
